The reasoning behind this verdict

Analyst conclusion

None of the 70 antivirus engines that checked it flagged this 12 KB .NET library. It matches a known-good software reference entry and has been submitted by about 1,300 sources since first seen on Oct 15, 2019. The sandbox runs showed no high-risk behaviour.

Where this verdict could be wrong3 caveats
  • The file is unsigned, so no publisher identity backs it.
  • Tags include detect-debug-environment and checks-user-input, though these are common in ordinary .NET game libraries.
  • The contacted-host reputation check was not available, though the sandbox recorded no network contacts.

These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.

Questions & answers

Short answers to the 6 questions people ask most about this file.

Is Accessibility.dll safe?
We found nothing harmful in Accessibility.dll. None of the 70 antivirus engines that checked it flag it. Use it only as part of a program you got from the developer's own website.
What is Accessibility.dll?
Accessibility.dll is a Windows library (DLL), about 12.3 kB. Its version information says it is “Accessibility.dll” (Mono Common Language Infrastructure). Version information is written by whoever built the file, so it is a claim, not proof of who made it. VirusTotal first saw it on Oct 15, 2019.
How many antivirus engines detected Accessibility.dll?
None of the 70 antivirus engines that checked it flag Accessibility.dll. That is a good sign, but not proof, so we also weigh who made it, how widely it is used and what it did in a test run.
What is the SHA-256 hash of Accessibility.dll?
The SHA-256 fingerprint of Accessibility.dll is c36813bdf03fbad922e6558756c3cc2956e6f74457003947fa4e91952445e19f, and its MD5 is 63c434b864ff270ce9fef43917dc8621. Two files with the same SHA-256 are identical, so use it to check you have exactly this file, not just one with the same name.
Is it safe to use Accessibility.dll?
We found nothing harmful in Accessibility.dll. The main caveat is where you got it: attackers sometimes spread malware under the name of real software, so get it from the official website. If your own antivirus warns about it, check the source before you ignore the warning.
How up to date is this analysis of Accessibility.dll?
This report reflects the scan on Oct 25, 2026. A file's fingerprint never changes, but antivirus engines keep learning, so a rating can change later. To get a newer result, scan the file again: we refresh the antivirus results when the saved ones are out of date.
